Thank you for your time. However, I'm sure you're aware that the information you're requesting is sensitive. I am therefore unable to make it public, as this would leave my endpoint vulnerable to denial-of-service attacks.

Nevertheless, I believe we can work with the example you provided. As you can see, the URL is correctly formatted. Once the URL endpoint is OK, the next step could be to check the secret name. You can test this by setting up a secret name and passing it through.

It's OK to do this again because I tested it using cURL.

Lastly, the important issue is that the status error code is not consistent with HTTP error codes and I can't find information about this error code.

In my experience with Hashicorp, they always take care of details like this.

Hopefully this helps to find the answer.
